“…Cuts on the absorption vertex radial position were optimised, based on MC simulations and a study of the Λ decay path, to select the targets with minimal contamination from other components. More details on the particle identification procedure can be found in [19] 5 K − absorption on two nucleons in the Σ 0 p final state In [19], a high purity sample of Σ 0 p events, from K − captures in the 12 C, was reconstructed. Σ 0 p is (together with Λp) an expected decay channel of the ppK − cluster, with the advantage to be free from the Σ N → Λ N' conversion processes.…”

Abstract. The AMADEUS collaboration aims to provide unique quality results from K − hadronic interactions in light nuclear targets, in order to solve fundamental open questions in the non-perturbative strangeness QCD sector, like the controversial nature of the Λ(1405) state, the yield of hyperon formation below threshold, the yield and shape of multi-nucleon K − absorption, processes which are intimately connected to the possible existence of exotic antikaon multi-nucleon clusters and to the role of strangeness in neutron stars. AMADEUS takes advantage of the DAΦNE collider, which provides a unique source of monochromatic low-momentum kaons and exploits the KLOE detector as an active target, in order to obtain excellent acceptance and resolution data for K − nuclear capture on H, 4 He, 9 Be and 12 C, both at-rest and in-flight.

“…Although the measured spectra are compatible with the hypothesis of a ppK − contribution, the significance of the result is not sufficient to claim the discovery of the state. We refer to [19] for the details of the analysis. The measurement of the, extremely rare, 4NA absorption process (K − + 4 He → Λt) is presently ongoing.…”
